The newest trailer for "Teenage Mutant Ninja Turtles," Paramount's live-action reboot of the popular comic book and animated series, shows the faces of each of the four vigilante reptiles for the first time.

It also features blink-and-you'll-miss-'em looks at their arch-nemesis, the bladed bad guy Shredder, and their mentor, the humanoid rat Splinter.

The trailer, which you can watch above, hews closely to the teaser video released last month: It opens with the same voice-over of William Fichtner lamenting, "Crime, violence and fear have run rampant. Our great city is being destroyed."

Masked men open fire and take over a subway station as explosions rock the city, and then it's time for the turtles to kick butt, while intrepid reporter April O'Neil (Megan Fox) tries to capture it all on her smartphone.

In the ensuing montage, Leonardo flips into action, Raphael draws his three-pronged sai, Donatello sports one of his signature inventions, and Michelangelo ties on his orange ninja mask.

Shredder's hulking silhouette can be seen stepping through a hole blasted in a wall, Splinter briefly twirls a sword, and April has a startling encounter with the turtles.

Director Jonathan Liebesman ("Wrath of the Titans," "Battle Los Angeles") appears to be taking his cues from the dark, gritty tone of the original Kevin Eastman and Peter Laird comic books of the early 1980s rather than the lighthearted animated TV series that ran from 1987 to 1996.

Though there have been a few goofy moments, such as the aforementioned April encounter, the footage released so far has yet to feature a single slice of pizza or cry of "Cowabunga!"

"Heroes are not born. They're created." That's one of the lessons of a new teaser trailer for the Michael Bay-produced "Teenage Mutant Ninja Turtles" movie — although in this instance, one might say they're re-created.

Even in a summer that's focused on creativity, with exceptional documentaries like "Amy" on Amy Winehouse and "What Happened, Miss Simone?" on Nina Simone, "Listen to Me Marlon" stands out. Autobiographical in nature, unconventional in structure, this is the story of Marlon Brando not as the world...

ABC News was last in the ratings in the summer of 1968, behind NBC's team of Chet Huntley and David Brinkley and Walter Cronkite on CBS. It was desperate to gain an edge on the more established networks' news teams.
